SPECIFICATION forming part of Letters Patent No. 591,020, dated october5, 1897.

Application tiled February 13, 18J6. Serial No. 579,140. (No model.)

T all L11/"1.0711, //I 'nbr/.H imm/rm Beit known that we, JOHN J. SPEERand RUDOLPH W. ZEDLITZ, citizens of the United States, and residents ofWaterbury, in the county of New Haven and State of Connecticut,haveinvented certain new and useful Im- Vproveinents in Locomotives, ofwhich the following is a specification.

Our invention relates to new and usefulV 1o improvements in feed-waterdistributers and combined blow-oft cocks and iire-extinguish ers forlocomotive orother engine boilers.

It is the object of our invention to provide for a locomotive-boiler adesirable and novel I5 feed-water distributer which will be adapted foruse in old or new boilers of any ordinary construction.

It is also an important object of our invention to provide a surfaceblower wherebyT the zo principal settlements of the water areconveniently discharged and the boiler thus cleaned, and, further, touse said surface blower in connection with a cock of specialconstruction and having a pair of check-valves. By

2 5 means of the above specially-constructed cock and valves we areenabled to get at (for repairs or other emergencies) either one of saidvalves without disturbing the other and without disabling the engine byhaving to draw 3o the fire. v

Referring to the accompanying drawings, which form a part-of thisspecification, the same reference-characters denote like orcorresponding part-s uponthe several figures, and

of which- Figure l is a central vertical section of a locomotiveprovided with our improvements. Fig. 2 is an enlarged detailcross-section on line a: c of Fig. l. Fig. 3 is a similarly-enlargedlongitudinal sectional view of our novel mechanism, which viewagreeswith Fig. l.

tion and plan View, respectively, ofthe combined blow-od cock andcheck-valves. Figs. 9, l0, and 1l are vertical longitudinal sectionalviews on line e' e of Fig. 7, showing the valve 5o of the cock in threedifferent positions, the purposes of which will be'later described.

Referring to the referencecharacters upon y Figs. 6 and 7 are a sideelevathe drawings, A indicates the boiler of a locornotive, B thenre-box, and C the lues running lengthwise of the boilers. p

D indicates our novel feed-water distributer, E the surface blow-off,and F the 'cock employed in connection therewith.

Our novel feed-water distributer is preferably located in the bottom ofa boiler immediately below the series of fines and over the water-supplypipe. lt is made of about Onequarter-inch sheet or boiler plate in twosections, so as to readily admit of its introduction into the boilerprior to being assembled. nate as l and 2, are secured together by meansof rivets or bolts 3 and are fastened to the boiler by lneans ofbrackets 4. Said sections l and 2 are placed at an angle of about onehundred and twenty degrees to each other and are broader in the centerover the supply-pipe than at their outer ends, thus insuring saidwater-supply traveling lengthwise under said `distributer until near theendsvhere it gradually escapes on each side by reason of the increasedspace between said distributers and the bottom of the boiler. The wateris in this manner distributed more evenly throughout the numerous iiuesand thereby increases its temperature before the same comes into contactwith said heated iiues. By the above means of distribution water of alow temperature is prevented from coming into direct contact with thefines, thereby reducing contraction and thus lengthening the life ofsaid i'lues. As before stated, the distributer is made angular incross-section-that is, higher' in the center than on the edges. Y Uponthe under side of the ridge of said distributerwe secure small hangers5, which support the main blow-off pipe E, running lengthwise therewithand provided with the two upwardly-curved branches 5 and 6, havingenlarged funnel-shaped mouths 7, which finish fiusli with the surface ofthe water in the boiler. The lower extremity of 'this blow-off pipe E is.turned downward, as at 8., in such a manner' that the end thereofterminates immediately above the discharge-cock, but is 'not connectedtherewith.

In view of the foregoing it will be apparent that when the cock F isopened, as in Fig. ll, the contents of the boiler has a direct and Thesetwo sections, which I will riesig# IOO free outlet through said cock,which would necessarily create a suction through pipe E and its branches5 and 6. Said suction acts to draw in the impure surface wat-er, andparticularly the Water from over the crownseat, where the majority ofsettlement takes place.

The combined blow-off cocks F and checkvalves will be best understoodwith reference to Sheet 3 of the drawings, and consists of a suitablebody 9, provided with a four-way valve 10, having the direct passage dand the intermediate passage Z9. This valve 10 is provided with cranks11 and 12, having suitable link connections 13 with operating-levers(not shown) in the cab and whereby said valve is operated to perform itsseveral functions. Upon each side of the body and in line with thecenter of the valve are provided threaded nipples 14 and 15, to whichare attached, by means of couplings 16, the checkvalves 17 and 18,respectively. Thus it will be apparent that said valves areindependently connected and can be detached separately Withoutdisturbinglhe other or effecting the operating of the engine.

By means of the convenient location of the check-valves with respect tothe cock and the mechanism for shifting the same it is possible to useone or both of them, as desired. They can also be used as afire-extinguisher independent of any action or assistance on the part ofthe boilers. In this case it is obvious that the hose-pipe to play uponthe tire would be connected to the under side of the cock, as shown indotted linesin" Fig. 3, and, further, that it would be fed by theinjectors through the check-valves and passages ay and b of the cockwhen in the position shown in Fig. 10. During the time the apparatus isbeing used as a iireextinguisher it is obvious that the boiler has gotto be fed with water and that the check-valves and their injectorscannot be used for that purpose, inasmuch as they constitute a part ofthe eX- tinguisher. Therefore we supply a third supply-pipe G and anintermediate passage c, through which the water is fed to the boilerduring the time the cock is acting as a fireextinguisher.

Having thus described our invention, what We claim, andrdesire to secureby Letters Patent, is-

1. The combination with the boiler of alocomotive having a Water-supplyinlet, of a water-distributer placed over saidinlet and consisting of anangular sheet-metal covering the length of which is greater than itswidth, and said width being greater at its center, means for securingsaid distributer to the boiler.

2. The combination with a boiler provided with a Water-supply cock, ofan invertedtrough-like deflector arranged over said supply, a blowpipeadjacent to said cock, connections of said pipe with the surface Waterin the boilers, whereby said impure surface Water is discharged throughsaidblowpipe and the cock above mentioned.

3. The combination with a boiler provided with a blow-off cock, of ablow-off pipe connected with the surface Water of said boiler andterminating adjacent to, but not connected Wit-h said cock, means foropening said cock and creating a suction through said blow-off pipe,substantially as described.

4. The combination with a boiler, of a bl0w off pipe therein, the mouthof which is substantially in line with the surface Water of the boiler,a cock adjacent to the mouth of said pipe, check-valves connected withsaid cock and adapted to feed the boiler therethrough, means formanipulating said cock to feed the boiler and also for blowing off thesame, substantially as described.
